tenuated state with low pressure air. so as to produce a combustible mixture for use in furnaces and the like.

The invention will be more fully described by reference to the accompanying drawings in which- Figure 1 is a longitudinal section of the spraying device. Fig. 2A a longitudinal section of a modified construction and Fig. 3 a longitudinal section of a modication in the form of the cone. y

The oil to be sprayed is fed into the pipe a either by gravitation or by a force pump, this pipe being constructed with a coned exit end b either integral therewith or screwed into or on to the pipe a. The pipe and its cone is'caused to revolve rapidly by mechanism external to 'the gas producer. Owing to the rapid revolution the oil travels in the direction of the arrows clinging to the walls of the pipe owing tothe centrifugal action, and as it emerges from the pipe a into the cone b, the centrifugal action causes the oil to cling tothe wallsof the cone as indicated by the arrows until it reaches the lip of the larger mouth of the cone from which it is thrown off into the chamber by centrifugal action in a thin film provided the edge of the cone is made straight, `as shown in Fig. Q, and is therefore` in a suitable condition for mixing with the air surrounding it in the carbureting chamber. It is preferred, however, to make the' edge of the cone in the form shown in Fig. 1 of the drawings or .in the modied form shown in Fig. 3.

As shown in Fig. 1, the outer edge of the cone is made with sharp` points b leaving at portions of edge c between them and as shown in Fig. 3 the edge of the cone may be serrated so as to form sharp points b the bottoms of thefserrations forming acute an les c.

is the oil travels up the cone b from the to the rapid revolution of the pipe and cone -it is thrown off in al thin film at the edge c or bottom of the serrations c and along the edges of the serrations. The sharp edges of the points b or of the serrations traveling at great speed pass -rapidly through this thin film of oil beating' and cutting it and thus breaking it up into very minute particles, practically forming it into vapor.

Fig. 2 shows a method of performing the same operation of spraying by means of a reversed c one b. Inl this case the oil fed into the pipe a passes out from the pipe into a chamber e formed in the interior of the cone b and thence through holesd surrounding the inner boss by which the pipe a is connected to the interior of the cone in the direction shown by the arrows, whence it travels on to the walls of the cone; The pipe and conebeing revolved` at a high rate of speed throws the oil from the outside of the mouth of theeone into a thin film, when the edge of the cone i-s straight as shown or asspray when the edge of the cone is provided with sharp points or is serrated, as previously describe -v Having thus described the nature of this invention and the best means I know of carrying the same into practical eect, I claim 1. In spraying apparatus for oil and the like, a pipe rotatable about its own axis and into which the oil is fed for delivery'- to a furnace or the like, and a spraying nozzle having an internally coned surface and an pipe a owing tothe centrifugal action due axially directed'open discharge end, said nozzle being detachably supported from and in a manner to be rotated by the pipe, and beingaxially alined and positioned. relatively to the pipe so that oil is delivered from the pipe directly into the internallyconed nozzle at its smaller end and is thrown outward from the edge ofits larger or discharge end by centrifugal force as the pipe is rapidly rotated, .said edge being constilike, a pipe rotatable about its own axis and into which the oil isfed for delivery to a furnace or thelike, and a spraying nozzle detachably supported from the forward end or discharge end of the rotatable pipe, saidy nozzle having an internally coned surface y Maaate terminating in a closed or imperiorate front end and being axially alined and positioned relatively tothe pipe so that the discharge ends of the pipe and the coned nozzle are oppositely directed and oil is delivered from the pipe directly into the internally coned nozzle and is discharged outwardly from thev edge of its larger or discharge end by centrifugal force as the pipe is rapidly rotated, said edge beingconstituted by a single surface of revolution and .formed With a plurality of'sharp projecting points.

- 3. ln spraying apparatus for oil and the like, a pipe rotatable about its own axis and into which the oil is fed for delivery to a furnace or the like, and a spraying nozzle having an internally coned surface and an axially directed open discharge end, .said

"nozzle being detachably supported from and in a manner to be rotated by the pipe, and being axially alined and positioned relatively to the pipe so that the outlet ends of the pipe and coned nozzle .are oppositely directed` and'oil is delivered from the pipe directly into the internally coned nozzle at its smaller end and is thrown outward from the edge of its larger or discharge end by centrii'ugal force as the pipe is rapidly rotated, said edge being constituted by a single surface of revolution and formed with a plurality of sharp projecting points, substantially as described.

ln testimony whereof l have signed my name to this specification in the presence of kone subscribing wltness.
